. 4 mm. Thepresent invention'relates to window constructions, and morein particular to a novel ,meta'llic double-hung window construction, andin the construction of the sash or closure members.

Among the objects of the invention is to provide a novel sashconstruction for a window whereby to provide a weather-tight engagementand mounting of the sash members in the frame. The invention comprehendsa construction, which is adapted for use wherever a weather tightclosure is desired.

. Another object of the invention is the provision of a novel resilientweathering means closure construction formed of metal and adapted to bemounted in a metallic frame and slidable therein. The invention furthercomprehends novel details of constructions of the sash or closuremembers and the frame, and in the means for locking and retaining thesash or closure members in their adjusted positions.

A further object of the invention is the provision of a novel sashconstruction comprising a pair of sash members slidable upwardly andadapted to be-raised into a well provided therefor in the frame of thewindow. The lower sash member is provided with means adapted to abut anextending portion on the upper sash member whereby said sash members maybe raised as a unit into the well provided therefor in the upper part ofthe window frame.

Another object of the invention is the provision of a pair of closureslocated inwardly of the transparent closures, and operable in a mannersimilar to said transparent closures whereby the lower closure contactsa portion of the upper closure, so that a continued lifting of the lowerclosure will likewise raise the upper closure to any desired openposition.

Further objects are to provide a construction of maximum simplicity,efliciency, economy, and ease of assembly, operation and maintenance;

and such further objects, advantages and capabilities as will later'morefully appear and are inherently possessed thereby.

The invention further resides in the combination, construction,andarrangements of parts illustrated "in the accompanying drawings, and5 while there is showntherein a preferred embodiment it is to beunderstood that the same is susceptible of modification and change, andcomprehends other details and constructions with-, out departing fromthe spirit of the invention.

In the drawings:

Fig. 1 is a view in side elevation of the outside of the frame;

Fig. 2 is a view in vertical cross section through the window frame.

Fig. 3 is an enlarged fragmentary view in hori-- zontal cross section ofthe frame and slidable closures therein, the view being enlarged to-moreclearly bring out the details of construction.

Fig. 4 is an enlarged fragmentary view in vertical cross section throughthe window construction taken on ,the line 4-4 of Fig. l.

Fig. 5 is an enlarged view in perspective of the details of constructionof the inner sash member and the latch mechanism for locking the same inadjusted position.

Referring more particularly to the disclosure in the drawings, theembodiment selected to 11- lustrate the invention comprises a windowframe I adapted to seat within and be connected to the side walls 2 of astructure, these side walls being provided with an opening for thereception of the window frame.

In the window frame are provided slidable sash members 3 and 4 alongwith slidable louvers 5 and 6. The window frame is shown as providedwith a sill 1 connected to the side walls by means of a metal trim 8, ahead jamb 9 and side jambs I connected to the side walls 2 by means ofmetal trim I2. 7

A head plate I3 also forms part of the window frame construction and isconnected to a metal trim M which in turn is connected to the side walls2 of the structure. Although no particular attaching means are disclosedfor connecting the various parts of the window frame to the walls, andthe metal trim to these various parts, it .is to be understood that anysuitable means such .as welding, bolting, or riveting may be employedfor connecting the various parts together to form a unitaryconstruction. The invention comprehends a unit construction which may beassembled at the factory and shipped for installation. 7 This headplatel3 bridges across and connects 1 the side jambs l0, and at itslower edge is provided with a channel shaped portion II adapted toreceive a part of the upper sash 2 when the same is in closed position.

Referring more particularly to the disclosure of the sash members, thesesash members 2 and 4 are of substantially the same construction and eachcomprises an upper pane seating section or rail l6, side rafls II, theupper sash being provided with a lower pane seating section or rail it,while the lower sash is provided with a lower pane seating section orrail it, each provided with a shoulder portion 20 adapted to support apane of glass 11 embedded in suitable retaining and weathering materialsuch as putty or the like and retained in place by glass retainingstrips or members 2| which are suitably secured to the glass seatingmembers or rails by bolts or other retaining means. v

The upper and lower glass seating members or rails l6 and it are eachprovided with longitudinally extending flanges or ribs 22, those of theupper sash 2 and the upper glam seating member or rail it of the sash 4are similar in construction and are provided with a channelshapedinterlocking portion 23 forming meeting rails and having a rearwardiy orinwardly projecting flange or rib 24 adapted to form a weather-tightclosure when the sash members are in closed position.

The channel shaped portions 23 have embedded therein weathering material25 such as felt or the like, the flanges or ribs 24 on the meeting railsprovided on the base or lower part of the sash I and the top or upperportion of the cash 4, interengaging to provide a weather-tight closurewhen the sash members are in closed position. The flange or rib 24 onthe meeting rail of the top or upper portion of the sash 3, is adaptedto seat within the channel l5 intermediate a flange or rib 26 providedon the head plate l2, and the side wall thereof so that when the uppersash is in lowered position, these interengaging parts provide aweather-tight seal.

The lower pane-seating section I! on the sash 4 is likewise providedwith longitudinally extending ribs or flanges 22, but these ribs orflanges are adapted to receive and retain a weather-strip 21 adapted toseat against and form a weather-tight closure with the sill when thislower sash is in closed position. In order to retain theweatherstripping 25, the flanges- 24 and 26 are all inwardly orrearwardly formed or undercut so as to retain the material without anyauxiliary holding means. The weather-stripping 21 is retained bysuitable holding means such as a screw 28 or the like.

In order to permit sliding movement of the sash members 3 and 4, theside jambs iii are each provided with stiles 29, each stile member beingof integral construction and retained by retaining strips 30 and 3|suitably attached to the jambs.

The stile members 29 are bent to form channel-shaped portions providedwith 'flanges 33 having inwardly extending projections 34 forming anintegral weather-stripping and adapted to receive therebetween theflanges or ribs 22 on the side rails or pane seating sections I! of thesash members. By reason of the inwardly formed projections 34 providedon the flanges, a weathertight sealing engagement is secured betweenthese members so as to provide a weather-proof construction. If desired,any suitable auxiliary weathering means may be employed in the channelsformed in the stiles. Each stile member 29 aosm'n is formed with alateral projection ll, the lateral projection of the outer stile membersseating beneath and retained by a. strip 2|, while the inner stilemembers are retained by a common retaining strip or channel member 2|which likewise forms a spacing member for the upper and lower sash.These strips 20 and II are provided with upstanding ribs or stops 24adapted to seat against the outer flanges 22 of the stiles and preventdisplacement thereof and damage thereto.

In order to permit proper adjustment of the lower sash to its fullheight and then of the lower and upper sash, this lower sash member isprovided with a latch 31 having a stationary handle 38 and an adjustablehandle 39 adapted to operate a latch member or bolt (not shown) in itsseating engagement with a rack 40 having oifset teeth 4|. As disclosedin Figs. 3 and 4, this rack is mounted between the stiles and may extendfor the full height of the window frame.

From the disclosure it will be seen that the lower sash member 4 is madeadjustable and may be adjusted throughout the height of the windowframe. However when this sash member has been raised to a position equalto the height of the sash 2, the meeting rail member at the top of thesash member 4 will abut a stop plate 42 formed on or connected to thetop of the upper sash 2, and thus any further lifting or raising of thelower sash will also raise the upper sash whereby the sash members maybe elevated as a unit.-

In order to permit ready opening of the window, the upper window isconnected to weights 43' attached to a cord orv chain 43" operating overa pulley 43 mounted on the jambs ll. Although the pulley is shown inconnection with the upper sash it is to beunderstood that either or bothof the sashes may be weight-hung.

In the present embodiment of the invention, one of the stop members 42is mounted at each side of the upper sash and is provided with aresilient insert 44 such as rubber or the like which is adapted to becontacted by the lower sash member.

The louvers or closures 5 and 4 are also adapted to be raised into thewell 45 provided in the top of the frame for the 'reception of the sashand louver members. Each of the louvers is constructed with T-shapedrafls 46 forming the top, bottom and sides of the louver construction.Each of these rails is provided with an undercut slot or groove 41. Inthe lower rail of the upper louver and in the upper and lower rails ofthe lower louver, this slot or groove is provided with an insert 48.

In order to permit sliding movement of these louvers, the jambs ID areprovided with an oflset portion or shoulder 48, a bar 50, and aseparating bar 5| adapted to be mounted in the lamb members by anysuitable means, the separating bar Ii providing an abutment andseparating means between the louver members 5 and 6. Intermediate theshoulder 49 and the separating bar SI and this separating bar and thebar 50 are thus provided channels or grooves forming a track for thelouver members to slide.

A plate 52 is attached to the upper rail 46 of the upper louver toprovide an abutment for the top rail 46 of the lower louver so that thislower louver may impinge against and raise the upper louver whendesired. Each louver is provided with a plurality of ventilatingopenings 53 which are preferably staggered so as to keep out theweather. Although the weight-hung feature is 15 only disclosed inconnection with the sash members it is to be understood that the louversmay likewise be so constructed.

From the above description and disclosure, it will-be readily seen thatthe invention comprehends a novel window construction including thedetails of the sash and louver members as well as weathering features inwhich the weathering means forms a part of the permanent windowconstruction. However, as the strips 30 and SI are readily detachable,the resilient stile members may be quickly removed and replaced. v

The entire window construction may be assembled at the factory and maythen be mounted as an assembly in a building construction. The parts maybe made of any gauge metal as desired, merely depending upon the use towhich the same is to be placed. When closed, the structure provides anefllcient weather-tight assembly.

Having thus disclosed the invention, I claim:
